GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 303,960, dated August19, 1884.

Application filed December 12, 1883. (No model.)

To all whom, it may concern..-

Be it known that 1, ROBERT J. W'ILsoN, of Milwaukee, in the county ofMilwaukee. and in the State of Vvisconsin, have invented certain new anduseful Improvements in Grain- Car Doors; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to grain-car doors, and will be fully describedhereinafter.

In the drawings, Figure 1 is an elevation of my improved device. Fig. 2is a transverse section thereof, and Figs. 8 and a are details.

A represents the sides of the car; B, the roof, and G the bottom, of thecar.

D is the door, which is adapted to slide vertically between the cleats(t a, the latter of which extends up only the height of the door, whilethe former extends the full height of the side of the car, and areprovided with the grooves I), partly covered by the slotted metallicplates B, both the grooves and the slots in the plates having the elbowor angle I) at the top.

E E are rods rising from the top of the door D, near each end, bentfirst outwardly, then vertically, and then inwardly at right angles, soas to enter the grooves b in the cleats a. and plates 13, and then thesaid rods end in oblong heads, 0. The slots in the plates B are of lesswidth than the grooves b in the cleats; and so, when the rods are inplace and the plates bolted or otherwise secured against the cleats, theheads of the rods are secured against the possibility of coming out, andat the same time have free vertical play in the grooves. Thus it will beseen that the doors can be raised up until they are free from the innercleats, a, when the heads 0 of the rods will be at the top of thegrooves I), and they can then be pushed into the angles 1/ of thegrooves, and the door will swing upward and inward upon these pivotalpoints to the carroof, and be there secured by the hooks F F, which aresimply angle-pieces pivoted in the caroroof-one at each corner of thedoorand which can be turned under the said door to secure it to theroof, or turned away from it to free it when it is to be let down. Ateach side of the door, near its top, there are secured to the cleats a athe racks G G, and to the front of the door are pivoted thelockingcatches g g, ada iited to lock the door and prevent it fromrising accidentally, but which can be freely released by the hand whenit is desired to elevate the said door, and at the center of the frontof the door, near the bottom, there is pivoted the cam H, having lever hintegral therewith, which can be readily turned by the foot of theoperator from the position shown in full lines to the position shown indotted lines in Fig. 1, and thereby serve to raise the door a few inchesfrom the carbottom, which will enable it to be easily raised by hand therest of the way to the top of the car, as described; but without suchstart it has been difficult to raise graincar doors, and heretofore theyhave been started by crow-bars, trucks, 820., which greatly injures thedoor and in time destroys its usefulness, permitting the escape of grainthrough the holes thusmade, which is all entirely avoided by myimprovement.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the doorways having the racks G G secured thereto,with the door D, provided with the locking-catches g g, adapted toengage with the said racks, and thereby preventthe door from rising,substantially as set forth.

2. The combination ot the door D with the cam H, pivoted near the bottomof the front of said door, and having leverh integral with the cam,whereby the same may be operated by foot, and the door raised therebyfrom the bottom of the car, substantially as set forth.

In testimony that I claim the foregoing l have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Visconsin, in thepresence of two witnesses.

ROBERT J. WILSON.
